1.Design of intelligent monitoring system for medical equipment
China Medical Equipment 2013;(12):44-45
Objective: Intelligent monitoring system of medical equipment can realize the intelligent dynamic management to equipment in the hospital wireless or wired network environment. Methods: Use of communication network, intelligent call, system monitoring and other means of science and technology to design the intelligent micro device state sensor. Results:System is mainly for hospital equipment, which can capture and management of medical equipment data. When the elderly have abnormal condition, it can send information through intelligent system, through identification and location, to realize the construction of equipment state information. Conclusion: Intelligent sensor in the system application can achieve the sharing of resources; realize the whole hand or full coverage of the intelligent health network system, providing an effective guarantee for the health of the masses.
3.Two methods for software auto update
Chinese Medical Equipment Journal 1989;0(02):-
This paper introduces such two methods for the software to detect and download its new version automatically as applying the mapped network drive in LAN and download through FTP in Internet. The implementation of auto running of the new version after update is also discussed.
5. Digital subtraction angiography of global cerebral blood flow of patients with central vertigo
Academic Journal of Second Military Medical University 2010;28(3):310-313
Objective: To investigate the morphological changes of cerebral blood vessels by digital subtraction angiography (DSA) in patients with central vertigo, so as to provide references for diagnosis and treatment of patients with central vertigo. Methods: Ninety-two patients suffering from central vertigo were subjected to cerebral angiography through femoral artery. The types, proportion, and distribution (site predilection and number of involved vessels) of the cerebrovascular abnormalities were observed and analyzed. Results: Of the 92 patients with central vertigo, cerebrovascular lesions were found in 137 sides, including 15 (10. 95%) anterior circulation lesions and 122 (89.05%) posterior circulation lesions. Thirty-one (33.7%) patients had 2 or more lesions. The most common lesion was vertibroarterial lesion accompanied with other cerebrovascular stenosis. The lesions included 39 (28.47%) sides with vertibro-basilar stenosis or occlusion, 13 (9.49%) sides with posterior cerebral artery stenosis or occlusion, and 59 (43.06%) sides with posterior circulation abnormalities. Conclusion: The posterior circulation stenoses or abnormalities might be the major reasons for central vertigo in middle- and old-age patients.

7.DWI LMMSE denoising using multiple magnitude directions.
Journal of Biomedical Engineering 2014;31(1):7-12
Because of the long acquisition time and spin-echo planar imaging sequence, diffusion weight magnetic resonance image (DWI) should be denoised effectively to ensure the follow-up applications. The commonly used denoising methods which induced from gray level image lack the use of the specific information from multiple magnitude directions. This paper, therefore, proposes a modified linear minimum mean square error (LMMSE) denosing method used for DWI. The proposed method uses the local information to estimate the parameter of the Rician noise and modifies the LMMSE using the information of multiple magnitude directions synthetically. The simulation and experiment of the synthetic DWI and real human brain DWI dataset demonstrate that the proposed method can more effectively remove the Rician noise compared to the commonly used denoising method and improve the robustness and validity of the diffusion tensor magnetic resonance image (DTI).

As a tumor suppressor, p53 is activated by numerous cellular and environmental signals, and plays a criticalrole in the cell cycle regulation, cell apoptosis and senenscence. The murine double minute (MDM)2 and double minute mu?rine 4 (MDMX) are two important regulators. MDMX is a p53 binding protein with strong sequence homology to MDM2, but lacks ubiquitin ligase activity, and which is unable to target p53 for proteasomal degradation. MDMX regulates p53 activity through its binding with p53 and its postranscriptional modification. MDMX in the closed and open structure binds to p53 to regulate its activity. As the main partner of MDMX, casein kinase 1 alpha (CK1α) disrupts the intramolecular binding in MD?MX in the cooperation to regulate p53 activity. The process of MDMX and CK1αin the regulation of p53 is multi-step and complicated. In this paper the mechanism of MDMX and CK1αin the regulation of p53 protein was reviewed.

Chinese Pharmacological Bulletin 1986;0(05):-
Effects of opiate receptor blocker-naloxone ( 5mg/kg) on somatosensory evoked potentials ( SEP ) in 6 cats was studied. Other 6 cats were treated with normal saline as control. Results showed that the amplitudes of SEP were significantly elevated after 0.5h of aaloxone infusion. The changes of SEP-CCTp or CCTmn were no significant. It was suggested that large dosage of naloxone can favorably improve the electrical activites of neuron in the centre nerve system.
